Hey there, glad I found this site.

I'll get straight to the point, my ball python has been a good, healthy, pet for about 3 years now. This week I fed him two live mice just as normal, but he didn't eat. This happens sometimes, so I left them in there for the night. This morning I checked to see if he had eaten them, but no... Instead they were alive, and he was laying sprawled out and very cold. There was some kind of fluid discharge near his mouth. I thought he was dead, but thankfully no.
He's ready to shed, but hasn't.

I put him into some warm water to heat him up and he's moving around normally, and acting fine... but...

I would deeply apriciate any advice you could provide.

Thanks!
